Abstract
The reset circuit includes a first current mirror coupled to a first terminal of a power supply. A second current mirror is coupled to a second terminal of the power supply. First and second switches couple the first current mirror to the second current mirror. A threshold detector provides a first signal when a current differential between the first and second current mirrors exceeds a predetermined threshold. A first shunt shunts the first current mirror to the first terminal. A second shunt shunts the second current mirror to the second terminal. Buffering circuitry controls the first and second switches and the first and second shunts in response to the first signal. The buffering circuitry further provides a buffered reset signal from the first signal. The buffered reset signal transitions from a first level to a second level in response to the first signal. The switches and shunts reduce the biases on the threshold detector and current mirrors.
